5- DDR2 clock and DQS P/N traces must be routed as 100 Ohms Differential pairs. Traces width and gap according to PCB stackup.
4- Length of all Data signals between Byte Lane should be matched together (<400 mils).
BCM7440 DDR2 2x16 --> Design notes and Layout Guidelines:
1- Place 121 ohms clock termination at the end of the differencial trace.
2- Pin swaping can only be done on data lines inside each group of 8 bit (Byte Lane).
3- Length of all Data signals into a Byte Lane should be matched together (<100 mils).
6- When developing the PCB floor plan, the proximity of the DDR2 device to the memory controller is an important factor.
- To avoid the use of external address termination on high-speed DDR2, the address trace length should be less than 2.5in.
* If those requirements can not be reached, refer to JEDEC JESD79-2B standard for design rules and terminations.
